APPARATUS FOR SPINNING AND DOUBLING.

SPECIFICATION formingpart of Letters Patent No. 74=2,822,dated November 3, 1903. Application filed October 4. 1902. Serial No. 125,891. (No model.)

To all whom, it may concern.-

Be it known that I, THOMAS AsHWoRTH, a subject of the King of Great Britain and Ireland, residing at Lynwood, Urmston, near Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Apparatus for Spinning and Doubling Cotton and other Fibrous Substances, of which the following is a specification.

to This invention relates to improvements on the subject-matter of a prior patent of the United States of America granted to me,bearing date March 7, 1899, No. 620,824.; and the objects of the present invention are to simr5 plify and improve the construction and application of the light wire brake-frames and also of the looped chains connected thereto (as described and referred to in the specification of such prior patent) for applying and regulating the drag upon the spindles of such apparatus; and I do hereby declare that the following is a full, clear, and exact description of my said invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying sheet of drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 on the drawings is a front elevation (extended or displayed) of myimproved brake-frame and chain. Fig. 2 is a side elevation thereof, showing its position when applied to the spindle; and Fig. 3 is a sectional plan View of the brake-frame without the chain.

According to my present improvements I make the light brake-frame all of a single piece of wire bent in such aform that it requires no 0 pins or studs to be fixed in the bolster for attaching it thereto, and at the same time it can be readily attached to and detached from the hanging or looped chain, and facility is afiorded for securing the small felt roller thereto and 5 removing and renewing the same when required. One end of the piece of wire at a,Fig.1, is left straight and rather longer than the felt roller b, which is placed thereon. The wire is then bent at a right angle, so as to form one arm 0 of a bell-crank lever. The wire is then turned inward for, say, about a quarter of an inch or less and then doubled closely back again, as shown at d, so as to form a pin or fulcrum, which is let into ahole drilled in the side of the bolster e, which carries the spindle e as shown at Figs. 2 and 3. It is then bent at a right angle again, so as to form the other arm f of the bell-crank lever, at the end of which it is bent outward at a right angle and doubled closely back again, so as to form a pin or fulcrum g, to which one end of the hanging chain is to be attached. The wire is thencarried straight across to the width required, as shown at h, and bent in exactly the reverse way, so as to form the other side of the frame, the forward end ct being formed into a curl or loop, as shown, to embrace the end of the straight piece a, first mentioned,which carries the felt drag-roller b. The chain which hangs in a loop upon this wire frame (see Fig. 2) is somewhat similar to the graduated chain (marked h and shown on Sheet 3 of the drawings) described in the prior specification hereinbefore referred to; but instead of being graduated to be heavier midway of its length than at its ends the chain is now made lightest at the end connected to the brake-frame and heaviest at its other end. Instead of making the chain entirely of links of sheet metal threaded onto pins of Varying lengths riveted at the ends (as shown on Sheet 3 of the drawings attached to my former specification before alluded to) I prefer to make the said chain with only a single row of links i upon each side (see Fig. 1) separated by tubes or rollers j of Varying lengths and diameters supported upon pins 10, the ends of which are riveted outside the single links 1', above referred to. By constructing the wire frames and the looped o chains used in connection therewith in this improved manner the apparatus is rendered less complicated, and a considerable economy in the cost of manufacture is effected, and the method of attaching and disconnecting the parts to and from each other and to and from the frame is greatly facilitated.

I claim as my invention- 1. In combination with abolster,drag-roller and chain, a wire frame of one piece, one part I00 forming the spindle for the drag-roller, parts bent inwardly to form a fulcrum adapted to.

fit in the bolster and a part on which said chain is hung, substantially as described.

5 2. A one-piece wire frame, bent to form parts g g, a chain hung on said parts, two arms ff extending therefrom and having bent-in portion (1, cl, the extremities cc of such arms f f being adapted to carry a drag-roller, in

10 combination with a bolster having recesses in which the portions d 61 may fit to form a fulcrum, substantially as described.

3. In combination with a light frame formed from asingle piece of bent wire, a looped chain 15 adapted to be hung upon such light frame,

and composed of a single row of links upon each side, with tubes of varying lengths and diameters, pins carrying the tubes, the ends Witnesses:
